I have an internal bug filed complaining that FreeBSD disables wake-on-lan on the hardware. This means that if you boot, say, Linux, even Knoppix as a quickie, and then shutdown, if the hardware supports it, it will be left in a state where a magic-packet wakeup will work. However, even if I boot up a FreeBSD kernel with NO em driver, and then shutdown, it undoes the WOL setup. Now, I would like to have explicit WOL support added into the em driver, but before I even worry about that I need to understand where the kernel turns this off without the driver even needed. I've looked around at the dev/acpi and arch/acpi code and at least so far I'm having a hard time getting an adequate picture to know how it happens. Jack
